How to find a shorted mosfet - safe & fast, no thermal camera or multimeter

[Evhen_Velikiy]

Hi Sorin! Totally agree with your methods in this video. But I have important addition! Like with GPU, when you have several phases in parallel you cant point exactly which mosfet is shorted. But there is a way! If the power from your power supply going through dead mosfet its also going through its coil! So you can take multimeter and measure voltage across coils and find exactly which one is under load right now! See, very simple! No need for thermal camera and no need to push high current, even 0.1A is enough to detect short circuit this way.

've been following electronic channels for a long time, I haven't come across such an exciting course in a long time. You showed us a method that is far from modern tools. That's the old school rocks over the tool-mania. Thank you Professor.👏

I have been following you for a long time and you are a great teacher and have interesting videos. Please ignore the negative comments and be sure that most people think only the best about you. I learned a lot from you and I'm still learning and it means a lot to me to look at some of your work at least one day. Thank you for that and greetings from Germany 😊

This man is ablolutetely best in electronics repair.. A genious of epic proportions. I have followed him for years.

You're the man Sorin! You found what works for you and you share it with your members. You are very talented and have a big heart. Thank you for being you!

Thanks for another great lesson professor Sorin 😊

Hi, I am a beginner student of electronics and this video taught me very well. If you post such videos for beginners, we will learn more. It's great. Keep it up.

You did an amazing job Mr. Sorin.
I always use coils to detect the short circuit, without a thermal camera or voltage injector, because the coils can never be connected to the ground, and that method that you used can lead to the exact place where the shorted component exists not just the MOSFET but any component that can cause a short to the ground like a capacitor, diode or IC.
Note :
When you short the two coils Next to GPU to the ground the voltage drops to 0.1 volts because that's coils are connected to the same power rail (+VCC GFX), because generally the CPU and GPU can have two power channels or more, and all that channels are connected to the same power rail (+VCC_Core or +VCC_GFX).
Nicely done keep going.

This is one of the most versed videos made for this matter, Sorin. Thank you! 🤗 Although probably the title should say “CC/CV power supply required”, it's fine. Excellently well explained.
Concerning what you say about a “short killer”, which is something you mention hearing somewhere (Discord), and that it “triggers” you because somehow you find people using it incorrectly (“blood boils” and “insane”, you say): I know this well, Sorin, I know. It has to do with mind programming, and these things which you find @#$% are actually triggering something in you, and you react. The trigger most likely has to do with a negative mind program which you need to give up from or transmute (with the assistance of a good mind reprogramming healer if you can't by yourself) or at the very least you must learn to disable the trigger in you, so it no longer triggers you or it stops having a negative effect on you. I know this well, Sorin, and unless they are really willing to learn you cannot stop dumbass people from being dumbass; it's them who must change themselves.
Thanks again. 🤗

The other day I was watching one of your old videos about finding a short and you explained more or less the same thing and some of the videos are about 5 years old. This has been going on for too long and the connoisseurs will always try to be better than the master and I have seen it on so many platforms😅. Quote from NF "You cannot stop the world from complaining" and you cannot make them "better than factory"😂 ..We must remember it is part and parcel of the world going around at the speed of 30 kilometers per second in orbit around our Sun😅 Thank you Sorin for this wonderful lesson.

When I had just started watching the video I said to myself, "this is going to be interesting". So I made myself a cup of coffee and watched the rest. I was right it was interesting and informational. So now it has been saved and liked. Thanks Sorin for making this educational video.

Thank you so much Sorin. I already do a lot of motherboard repairs. This has helped me find a short circuit on a rtx3090. ( which i could not work out due to no proper heat signal) agree with you. Those things that shall not be mentioned are a waste of money!

[ros]

try to never let people trigger you. happens every day, keep the good thing going my friend, im learning from you. thanks

[greentech]

The Genius Sorin. Love your methods ❤ This can be only from experience and a gifted mind for electronics

[tinman]

Nice, sweet, and to the point! I’ve been following you for a while and I find your instructions very informative! Thank you for what you do!!!

[QARepair]

Thank You for this video, one of the best ! I think it will refresh brain even for experienced in repair, sometimes need to think simply logical but our heads is full and brain tricking us to look more complicated

[icommandoi]

Someone was looking for a short finder but instead found Sorin's short fuse :D hahaha love it, and great info on using the power supply.

[kpelectronics]

Absolutely right people wants easy ways without knowing that sometimes its not correct. Something that boils my blood when I see some people wanting to teach in some youtube channels but they don't have it right . They think they do but at the end with what you learned you know they are not right .

Thank you for showing a simple, safe and practical method to locate shorted MOSFETs and capacitors using only a good power supply.
In several places in the video, you read the voltage as 'zero point zero nine', 'zero point zero five', 'zero point zero one', etc instead of saying 'zero point nine', 'zero point five' and 'zero point one'.
It will be nice if you can repost the video showing the corrections in text.

I repaired a shorted mosfet using "a sorin style" now the problem was when the customer asked me what I had Sorin fuse🤣🤣🤣 and it worked nonstop ...but am hoping to replace that mosfet after some time coz the customer was in a hurry
